METHOD OF MAKING SWITCH-CLIPS.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed November 28,1902. Serial No. 133,002.

To all whom it may concern:

Be it known that I, WALTER J. RIoKEY, a citizen of the United States, residing at Schenectady, county of Schenectady, State of New York, have invented certain new and useful Improvements in Methods of Making Switch- Clips, of which the following is a specification.

This invention relates to a method of making switch-clips for electric switches; and its object is to simplify the method of making the same and cheapen the cost of manufacture. To this end the switch-clips are cut from a rolled or drawn bar of solid metal, preferably of I section, said bar having flanges of the thickness required for the base of the clip and aweb of the thickness of the blade of the switch plus the thickness of the jaws of the clips.

In the accompanying drawings, Figure 1 is a perspective view of the I-bar. Fig. 2 shows a piece cut from the I-bar with a portion of the web punched out. Fig. 3 shows the piece cut into two similar blanks. --Fig. A shows the block of insulation and the rivet for bolding it, and Fig. 5 shows the completed clip.

In making the clips in accordance with my improved method a piece 2 is cut from the I-bar 3 and a narrow portion of the web is punched out, leaving a hole 4 extending from one flange 5 to the other. This hole should be cut by a tool as narrow as possible to avoid waste of material. The web portions 6 are then severed at one end close to the flange, one being cut at one end and the other at the other end, so as to make two similar blanks, as shown in Fig. 3. Holes 7 are then drilled and tapped for the fastening-screw and the bridging-screw and a hole 8 for a purpose hereinafter set forth. A slot is then milled in the portion 6 to form the jaws of the clip,

which are preferably curved outwardly at the top and slit at 9, as shownin Fig. 5. Ablock 10 of insulation is then placed at the bottom of the space between the jaws, and a rivet 11 is driven through the hole 8 and the block to secure it in place. The clip is then complete.

The advantage of my method of construction is that the jaws of the clip are integral with the base, thus giving better conductivity and making a stronger mechanical job than when the jaws are soldered to the base. The block can thus be made with the minimum of metal that will carry the current for the designated size.

What I claim as new, anddesire to secure by Letters Patent of the United States, is

1. The method of making switch-clips, consisting in cutting off sections of an I-bar, and cutting the web of each section transversely and longitudinally in opposite directions from the ends of said transverse cut.-

2. The method of making switch-clips, consisting in cutting off sections of an I-bar, cutting the web of each section transversely near the middle of the section, and cutting it longitudinally close to the flanges in opposite directions from the ends of said transverse cut.

3. The method of making switchclips, which consists in cutting a piece ofl an I-bar, cutting the web of the piece between the flanges, severing the remaining portions of the web close to the flanges, one at one end and the other at the other end, and slotting the web portion on each of the two blocks thus formed.

In witness whereof I have hereunto set my hand this 25th day of November, 1902.

IVALTER J. RIOKEY.
